Dial 9-1-1 for speed

Porsche is giving its rabid fans a taste of what is to come at this September’s Frankfurt Motor Show: the 911 GT2.

This edition of the GT2 continues the previous model’s reign as the most extreme 911 for the road. Its optimized, twin-turbocharged, 3.6-liter flat-six makes 50hp over the garden-variety 911 Turbo, or 530hp and 502-lbs.ft. of torque, figures good for a 3.7-second run to 62 mph and a stunning 204 mph top speed.

Lest this absolute power be considered socially irresponsible, Porsche engineers note that the 3,175-pound car still achieves 22.6 imperial mpg (18.8 U.S. mpg) in the New European Driving Cycle, quite a feat considering its six-pound-per-hp rating. Also noteworthy are the GT2’s emission controls, which use a rear silencer and tailpipes made from titanium.

On European roads in November, the 911 GT2 will cost the equivalent of $261,163 after taxes.
